Abstract

A daisy chained clock distribution scheme for distributing a clock signal from a central communications clock driver to the nodes of a massively parallel multi-processor computer or supercomputer. The daisy chained clocking scheme is implemented using point-to-point clock distribution of a differential clock signal to the communication nodes of a plurality of processors in a multicomputer system or to components connected to a common bus in a high speed microprocessor system. Differential signaling is employed wherein the differentiality is maintained including through silicon. In an alternate embodiment, the clock pulse is also regenerated in each node component.
